LTC6995HS6-2#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6995HS6-2#TRMPBF is a silicon oscillator from the TimerBlox family, designed for long duration timing events. It features a programmable period range of 1.024ms to 9.54 hours (29.1µHz to 977Hz). The output clock period is determined by an internal master oscillator and a programmable frequency divider (NDIV) with eight settings from 1 to 221. The device operates on a single supply voltage of 2.25V to 5.5V, consuming between 55µA and 80µA depending on the clock period. It includes a reset function to stop oscillation and clear dividers, with active-low reset polarity specific to the -2 version.

Programmable Timers And Oscillators Feature Summary

• Programmable period range from 1.024ms to 9.54 hours using a single RSET resistor and DIV pin configuration
• Active-low reset input (LTC6995-2) with selectable output polarity via the POL bit
• CMOS output driver capable of sourcing/sinking 20mA with low rise/fall times
• Operates over extended temperature range (-40°C to 125°C) in a 6-lead TSOT-23 package

Programmable Timers And Oscillators Applications

• Power-on reset timers
• Long time one-shot circuits
• Watchdog timers
• Periodic wake-up calls
• Heartbeat timers

Programmable Timers And Oscillators Procurement Notes

Verify the component matches the specified -H grade for -40°C to 125°C operation and the -2 suffix for active-low reset functionality. Confirm the #TRMPBF suffix indicates tape and reel mini packaging. Ensure compatibility with the required NDIV settings and RSET values for the target frequency.

Programmable Timers And Oscillators Selection Notes

Select this variant for applications requiring extended industrial temperature ranges and active-low reset control. Choose the -1 version if active-high reset is preferred. Use Table 1 in the datasheet to determine the correct resistor network for the DIV pin based on the desired NDIV and output polarity. Ensure RSET tolerance meets the required frequency accuracy specifications.

Programmable Timers And Oscillators Part Context

This part belongs to the LTC6995-1/LTC6995-2 series within Analog Devices' TimerBlox family. The HS6 designation indicates the H temperature grade (-40°C to 125°C) and S6 TSOT-23 package. The -2 suffix denotes the active-low reset logic. Other variants include C (commercial), I (industrial), and MP (military) grades with different temperature ranges and packages.

Programmable Timers And Oscillators Replacement Considerations

Direct substitutes include other LTC6995 variants with matching temperature grades and reset polarities, such as LTC6995IS6-2#TRMPBF for industrial grade or LTC6995MPS6-2#TRMPBF for military grade. Verify package compatibility and electrical parameters before substitution.
